<Premium gripping part>
A crane mechanism 10 and an XY stage 12 for moving the crane mechanism 10 substantially horizontally in the storage portion 3 are provided on the upper part of the housing 2. Further, a control board 60 for electronically controlling these is built in an operation table 16 projecting from the front portion of the housing 2 of the game machine 1 toward the front. In this embodiment, the prize gripping portion is composed of the crane mechanism 10, the XY stage 12, and the control board 60.

The XY stage 12 is a linear motion stage whose operation is controlled by the control board 60 based on an operation input instruction of the player, and is realized by, for example, a gantry type stage.

As best shown in FIG. 3, the XY stage 12 is provided on the upper portion of the storage portion 3 along the X-axis direction, and further, a pair of X-axis rails provided parallel to the front and rear ends of the housing 2. It has a 12a and a pair of X-axis sliders 12b that are movable above each of the X-axis rails 12a.

At least one of the X-axis sliders 12b detects a drive unit that drives the X-axis slider 12b with respect to the X-axis rail 12a and a relative position of the X-axis rail 12a with respect to a predetermined reference position by electronic control of the control board 60. A position detection unit is provided (both are not shown). The position detection unit is realized by, for example, a distance measuring sensor, a rotation speed counter of the drive unit, or the like. The position detection information detected by the position detection unit is fed back to the control board 60.

The XY stage 12 further includes a Y-axis rail 12c laid between a pair of X-axis sliders 12b along the Y-axis direction, and a Y-axis slider 12d movable along the Y-axis rail 12c. The Y-axis slider 12d has the same configuration as the X-axis slider 12b, and can be slidably moved with respect to a predetermined reference position of the Y-axis rail 12c under the control of the control board 60.

As shown in FIG. 1, the crane mechanism 10 has a crane base 10a having a built-in lifting device and the like. The crane base 10a is suspended and fixed from the Y-axis slider 12d, and the crane head 10b is lifted and controlled by electronic control of the control board 60, and the prize gripping arm 10c provided on the crane head 10b is opened and closed. ..

The crane mechanism 10 is moved to a desired upper position of the field 40 by the XY stage 12 in response to an operation input instruction of the player. Then, when the movement operation is completed, the operation is controlled so that the crane head 10b is lowered toward the field 40 with the prize gripping arm 10c open.

If the descent motion control is performed, the crane mechanism 10 is gripped so as to close the prize gripping arm 10c, and then the crane head 10b is pulled up so as to be pulled up above the field 40. If the prize can be gripped well when the prize gripping arm 10c is closed, the prize will be won. That is, a series of controls from the descent motion control to the gripping motion control and the pulling motion control are the prize acquisition motion control in the present embodiment.

The coin computer 19 is a device that outputs a detection signal to the control board 60 when a coin insertion is detected, and is also called a coin counter or the like. The coin insertion slot 18 and the coin calculator 19 can be replaced with a prepaid card or credit card insertion slot and a reader / writer device for those cards. Of course, both may be installed side by side.

In the game machine 1 of the present embodiment, when a player inserts a coin set in advance as a game consideration, a predetermined value of "play points" required for game play is given. The point display panel 20 is a means for displaying the current balance of play points, which is realized by, for example, a 7-segment display or a liquid crystal display, and is displayed and controlled by a control board 60.

In the present embodiment, the crane mechanism 10 is moved from the home position of the XY stage 12 (for example, above the prize drop port 7) to a desired position in the field 40, and the game is played with the aim of acquiring the prize by the crane mechanism 10. As a rule, the movement operations in the X-axis direction (rightward when viewed from the front) and the Y-axis direction (depth direction) are set to be valid only once.

Therefore, the operation button 22 has a Y-axis direction movement button 22a that moves the crane mechanism 10 in the depth direction of the game machine 1 and a right direction of the game machine 1 in order to determine a target position where the crane mechanism 10 descends. It is provided with an X-axis direction moving button 22b for moving to.

More specifically, the XY stage 12 maintains the crane mechanism 10 at a predetermined home position at the beginning of the game. From there, the movement of the crane mechanism 10 by the XY stage 12 is started in response to the pressing of the movement buttons 22a and 22b, and the movement by the XY stage 12 ends when the movement buttons 22a and 22b are released.

Then, when the movement in each of the Y-axis direction and the X-axis direction by the XY stage 12 is completed, the acquisition operation by the crane mechanism 10 is automatically performed. That is, the operation is controlled so that (1) the crane mechanism 10 descends with the prize gripping arm 10c open, (2) closes the prize gripping arm 10c when it descends to a predetermined position, and (3) rises again.

Further, (4) the XY stage 12 is automatically controlled so as to move the crane mechanism 10 directly above the prize drop port 7, and (5) when the crane mechanism 10 reaches directly above the prize drop port 7, the prize gripping arm 10c of the crane mechanism 10 is pressed. The XY stage 12 is controlled so as to release the prize that has been opened and gripped, and (6) return the crane mechanism 10 to the initial position.

The number and types of operation buttons 22 are not limited to this, and may be appropriately set according to the game rules. For example, a trigger for inputting the start of descent of the crane mechanism 10 may be added, a joystick may be used instead of the Y-axis direction movement button 22a and the X-axis direction movement button 22b, and a lever, dial, touch panel, etc. may be used. You may use it.

The prize discharge unit 26 constitutes a passage in which the above-mentioned prize drop port 7 is used as an entrance and the opening provided on the front left side of the operation table 16 is used as a prize outlet 28 (exit). The prize dropped into the prize drop port 7 is introduced into the prize outlet 28, and the player can take out the prize from the prize outlet 28.

The prize outlet 28 is provided with a lid 29 whose upper end is rotatably supported by the housing 2. Therefore, when the prize falls into the prize outlet 28, the player can flip the lid 29 in the depth direction in FIG. 1 to open the prize outlet 28 and take out the prize. The prize discharging unit 26 has a detection mechanism for detecting the fall of the prize to the prize outlet 28 and a lid for preventing the opening and closing of the lid 29 when the prize has fallen to the prize outlet 28 by this detection mechanism. A closing mechanism (all not shown) is provided.

A program such as firmware used for controlling the operation of the game machine 1 is stored in the ROM 66, and when the power of the game machine 1 is turned on and the operation of the CPU 62 is started, this program is read out and executed by the CPU 62. The operation of the game machine 1 is controlled.

These CPUs 62 and the like are electrically connected to each other via a bus circuit 68, and are connected so that data can be read and written and signals can be transmitted and received. Further, the bus circuit 68 includes a coin detection device 71, a crane position sensor 72, a motion sensor 30, a door sensor 31, a Y-axis direction movement button 22a, and an X-axis direction movement button 22b via an I / O interface circuit 70. It is connected.

The I / O interface circuit 70 is a circuit that relays signals with various input / output units. For example, a plurality of types of I / O interface ICs that generate signals according to the standards of the connected input / output units may be included.

The coin detection device 71 is a device that accepts payment for game play. In the example of FIG. 1, the coin calculator 19 corresponds to this, but when a prepaid card, a credit card, or electronic money is accepted as a means of payment, it may be a reader / writer device for a card made of those recording media. ..

The crane position sensor 72 detects, for example, the current coordinates of the X-axis slider 12b and the Y-axis slider 12d with respect to the reference position of the XY stage 12. The crane position sensor 72 is realized by, for example, a rotary encoder, a distance sensor, a rotation sensor of gears and pulleys included in a drive system, and the like.

The CPU 62 transmits the current set value of the digital switch, the position coordinate information of the crane mechanism 10, the operation input information made to the operation button 22, and the motion sensor 30 and the door sensor 31 via the I / O interface circuit 70. The detection output can be acquired.

The XY stage driver 73, the crane driver 74, the elevating part driver 75, and the point display panel driver 76 are electrically connected to the CPU 62 via the I / O interface circuit 70.

The "driver" referred to here is an electronic element and a circuit capable of generating and outputting a control signal for driving and controlling a target display element, a driving element such as a motor, etc., in response to a control signal of the CPU 62. ..

Specifically, the XY stage driver 73 generates drive signals for the X-axis direction drive motor 12x and the Y-axis direction drive motor 12y mounted on the X-axis slider 12b and the Y-axis slider 12d, respectively.

Further, the crane driver 74 generates a drive signal for the elevating motor 10d of the crane head 10b of the crane mechanism 10 and the opening / closing motor 10e of the prize gripping arm 10c. The elevating unit driver 75 generates a drive signal for driving the stepping motor 50a of the driving unit 50 of the elevating unit 41 to move the field 40 up and down.

The point display panel driver 76 causes the point display panel 20 to display the balance of play points.
In the above configuration, the elevating control unit of the present invention is configured by the CPU 62, the I / O interface circuit 70, and the elevating unit driver 75.

The arithmetic element mounted on the control board 60 is not limited to the CPU 62, and may be configured to include various microprocessors such as a GPU (Graphics Processing Unit) and a DSP (Digital Signal Processor) as appropriate. Further, the configuration may include an ASIC (Application Specific Integrated Circuit). The IC memory of the RAM 64 or the ROM 66 may also include a RAM for a specific purpose such as a VRAM, a flash memory, or the like as appropriate.
<Operation of game machine 1>

Next, the operation of the game machine 1 of this embodiment will be described with reference to FIG.

When the power switch (not shown) is turned on and power is supplied to the control board 60, the operation shown in the flowchart of FIG. 14 starts. First, in step S1, the CPU 62 sets itself so that the CPU 62 can accept (enable state) the detection output from the motion sensor 30.

In step S2, the motion sensor 30 determines whether or not a player exists in front of the game machine 1, and if it is determined that a player exists (YES in step S2), the CPU 62 performs I / O in step S3. A drive command for the elevating unit 41 is sent via the interface circuit 70 and the elevating unit driver 75, and the elevating unit 41 causes the field 40 to perform an attract mode operation. Here, in the attract mode operation, as an example, the field 40 is continuously moved up and down by the elevating part 41 to call the attention of the player who seems to be in front of the game machine 1, and the player plays the game machine 1. It is a mode operation that creates an opportunity to make it.

In parallel with the attract mode operation of the field 40 being performed by the elevating unit 41, has the CPU 62 detected that the coin has been inserted into the coin insertion slot 18 by the player in step S4? If the judgment is affirmed (YES in step S4: coins have been inserted), the program proceeds to step S9 and the judgment is denied (NO: coins have not been inserted yet in step S4). And the program shifts to step S5.

In step S5, the CPU 62 determines whether or not a predetermined time, for example, 5 minutes has elapsed since the attract mode operation in step S3 was started, and if the determination is affirmed (YES in step S5), the program goes to step S6. When the transition is made and the determination is denied (NO in step S5), the program returns to step S3 and continues the attract mode operation.

In step S6, the CPU 62 stops the attract mode operation by the elevating unit 41, stops the field 40 at the uppermost position, and further, the CPU 62 sets itself so as not to accept the detection output from the motion sensor 30 (disabled state). Set.

In step S7, the CPU 62 determines whether or not the coin detection device 71 has detected that the player has inserted coins into the coin insertion slot 18, and the determination is affirmed (YES in step S7: coins have been inserted). If), the program proceeds to step S10, and if the determination is denied (NO: coin has not been inserted yet in step S7), the program proceeds to step S8.

In step S8, the CPU 62 determines whether or not a predetermined time, for example, 30 to 60 seconds has elapsed since the field 40 was stopped in step S6, and the determination is affirmed (YES in step S8), the program steps. Returning to S1, when the determination is denied (NO in step S8), the program returns to step S7 and determines whether or not the coin detection device 71 has detected that a coin has been inserted.

In step S9, it is determined that the coin has been inserted in step S4, that is, the player starts the game, and the CPU 62 stops the attract mode operation by the elevating unit 41.

Then, in step S10, the CPU 62 sends a drive command for the elevating unit 41 via the I / O interface circuit 70 and the elevating unit driver 75, and the elevating unit 41 causes the field 40 to perform a game mode operation. Here, the game mode operation is, for example, a mode operation in which the field 40 is continuously moved up and down by the elevating unit 41 as in the attract mode operation, but it is more than the vertical movement range of the field 40 in the attract mode operation. This mode has a narrow vertical movement range.

During the game mode operation in step S10, as described above, the player operates the crane mechanism 10 and the XY stage 12 by appropriately pressing the operation buttons 22 (Y-axis direction movement button 22a, X-axis direction movement button 22b). Performs a prize acquisition operation on the field 40. Therefore, the vertical movement range of the field 40 in the game mode operation is expected to affect the difficulty level of the player's prize acquisition, so the vertical movement range is set narrow. Of course, the difficulty level can be adjusted by the vertical movement range of the field 40 in the game mode operation, so that the vertical movement range of the field 40 in the game mode operation must be narrower than the vertical movement range of the field 40 in the attract mode operation. Absent.

When the game mode operation in step S10 elapses for a predetermined time, for example, 30 seconds to 60 seconds, the program shifts to step S11, and the coin detection device 71 indicates that the CPU 62 has inserted coins into the coin insertion slot 18 by the player. Determines if has been detected. Then, when the determination is affirmed (YES in step S11: coin is inserted), the program returns to step S10 and restarts the game mode operation, and the determination is denied (NO: coin is still inserted in step S11). The program proceeds to step S12.

In step S12, the CPU 62 determines whether or not a predetermined time, for example, 30 to 60 seconds has elapsed since the end of the game mode operation in step S10, and the determination is affirmed (YES in step S12). When the process proceeds to step S6 and the determination is denied (NO in step S12), the program returns to step S11 and determines whether or not the coin detection device 71 has detected that the coin has been inserted.
<Effect of this example>

As described above, in the game machine 1 of the present embodiment, when the field 40 is in the uppermost position by the elevating portion 41, the field 40 is provided by the side cover plate 52 and the notch cover plate 53 provided in the field 40. Since the gap between the frame 9 and the frame 9 and the gap between the field 40 and the base 6 are covered, the field 40 is moved by the elevating portion 41 with the body of the administrator or the like in these gaps. Can be prevented from doing so. As a result, the administrator and the like can be protected from the vertical movement of the field 40 by the elevating unit 41.

Further, even when the field 40 is in the lowest position by the elevating part 41, the gap between the opening 8 and the base 6 and the field 40 and the prize drop opening are provided by the side cover plate 52 and the notch cover plate 53. Since the gap between the two and the field 40 is covered, the field 40 is moved by the elevating part 41 with the body of the administrator or the like in the gap even when the field 40 is in the lowest position by the elevating part 41. Can be prevented from doing so. As a result, the administrator and the like can be further protected from the vertical movement of the field 40 by the elevating unit 41.

Further, the side cover plate 52 provided at the edge of the field 40 on the opening 8 side and extending downward from the edge, and the edge of the notch 40a of the field 40 are provided at the edge of the notch 40a. Since the notch cover plate 53 extending downward from the portion is provided, the body of the administrator or the like comes into contact with the side cover plate 52 and the notch cover plate 53, so that the body of the administrator or the like is in contact with the field 40 and the frame. It is possible to prevent entry into the gap between the body 9 and the gap between the field 40 and the base 6. As a result, the administrator and the like can be further protected from the vertical movement of the field 40 by the elevating unit 41.

Further, when the field 40 is at the uppermost position by the elevating part 41 and the lower end portion 52a of the side cover plate 52 is provided so as to be located below the frame body 9, the body of the administrator or the like is on the side. By contacting the portion cover plate 52 and covering the gap between the field 40 and the frame body 9 with the side cover plate 52, it is possible to prevent the body of the administrator or the like from entering the gap. As a result, the administrator and the like can be further protected from the vertical movement of the field 40 by the elevating unit 41.

Further, when the field 40 is at the uppermost position by the elevating portion 41, the lower end portion 53a of the notch portion cover plate 53 is provided so as to be located below the base 6, so that the body of the administrator or the like is notched. By contacting the portion cover plate 53 and covering the gap between the field 40 and the base 6 with the notched portion cover plate 53, it is possible to prevent the body of the administrator or the like from entering the gap. As a result, the administrator and the like can be further protected from the vertical movement of the field 40 by the elevating unit 41.

Further, a door sensor 31 for detecting the open / closed state of the door portion 5 is provided, and when the door sensor 31 detects that the door portion 5 is in the open state, the CPU 62 raises and lowers the door via the I / O interface circuit 70 and the elevating part driver 75. Since the control for stopping the vertical movement of the field 40 by 41 is performed, when the administrator or the like opens the door portion 5 to perform the prize replenishment work or the like, the door sensor 31 detects the open state of the door portion 5. The operation of the elevating unit 41 is stopped. As a result, it is possible to prevent the elevating unit 41 from moving unexpectedly, and it is possible to further protect the administrator and the like from the vertical movement of the field 40 by the elevating unit 41.

Then, it has a motion sensor 30 that detects the proximity of the player to the game machine 1, and the CPU 62 starts the operation of the elevating unit 41 when the motion sensor 30 detects the proximity of the player. The operation of the elevating unit 41 can be automatically started by the proximity. As a result, the player can be made interested in the game machine 1, and the interest of the game can be enhanced.

Here, if the door portion 5 is open, the operation of the elevating portion 41 is stopped by the door sensor 31, so if the door sensor 31 is present, the administrator and the like can be further increased from the vertical movement of the field 40 by the elevating portion 41. It is also thought that it can be protected.

However, there is a possibility that the administrator or the like will force majeure to touch the door sensor 31 while the administrator or the like is performing the prize replenishment operation or the like, and as a result, the operation of the elevating unit 41 may be restarted. In the game machine 1 of the present embodiment, even if such a situation occurs and the body of the administrator or the like tries to invade the gap between the field 40 and the frame body 9, the body of the administrator or the like covers the side surface. The plate 52 abuts on the region A shown in FIG. 11 to prevent the body from entering the gap between the field 40 and the frame 9. Similarly, even if the body of the manager or the like tries to invade the gap between the field 40 and the base 6, the body of the manager or the like comes into contact with the area B or C shown in FIG. 11 of the notch cover plate 53. The body is prevented from entering the gap between the field 40 and the base 6.

As described above, according to the game machine 1 of the present embodiment, regardless of the vertical position of the field 40, even when the field 40 is moved up and down by the elevating portion 41, the space between the field 40 and the frame 9 is reached. Since the gap between the field 40 and the base 6 is always covered by the side cover plate 52 and the notch cover plate 53, the manager or the like can be moved from the vertical movement of the field 40 by the elevating part 41. It can be reliably protected.

Further, if the door portion 5 is open, the operation of the elevating portion 41 is stopped by the door sensor 31, and the lid 29 is closed by the detection mechanism and the lid closing mechanism unless the prize is dropped into the prize outlet 28. Therefore, it is highly unlikely that the player will enter the storage unit 3 and the prize discharge unit 26. However, if the prize falls into the prize outlet 28, the lid 29 can rotate, and if the elevating unit 41 controls the field 40 to continue moving up and down in this state, the player controls the prize outlet 28. There is a possibility that the body may invade between the field 40 and the base 6 when the action of putting a hand in the lid and taking out the prize is performed.

In the game machine 1 of the present embodiment, since the gap between the field 40 and the base 6 is covered by the notch cover plate 53, not only the administrator but also the player can be sure from the vertical movement of the field 40 by the elevating part 41. Can be protected.

As a matter of course, when the detection mechanism detects that the prize has fallen into the prize outlet 28, it is better to control so that the vertical movement of the field 40 by the elevating unit 41 is stopped.
[Second Example]

In the above-mentioned first embodiment, the prize outlet 28 is provided only on the left side of the housing 2 (to be exact, the operation table 16), but in the game machine 1 of the second embodiment shown in FIG. 15, the front surface thereof. The prize outlet 28 is provided over substantially the entire width direction of the above. Therefore, the prize drop port 7 provided on the base 6 is also provided over substantially the entire width direction of the base 6 corresponding to the prize outlet 28, and the notch 40a of the field 40 of the elevating device S is also provided. It covers the entire opening 8 side end of the field 40.

In such a game machine 1 of the present embodiment, it is sufficient to omit the side cover plate 52 and provide only the notch cover plate 53.
(Other)

The details of the prize acquisition game machine of the present invention are not limited to the above-described embodiment, and can be appropriately changed without changing the gist of the present invention. As an example, the shape of the field 40 and the cutout portion 40a are not limited to the above-described embodiments, and can be appropriately changed according to the shape of the storage portion 3 of the game machine 1 and the like. For example, in the case of a prize acquisition game machine capable of arbitrarily opening a part of a field, this opening corresponds to a notch of the present invention.

In addition, as shown in FIG. 12, the field 40 is divided into a main body portion 40b and a frame body end portion 40c provided at the frame body 9 side end portion, and these main body portions 40b and the frame body end portion 40c are separated. It may be connected by a hinge 56. As shown by the arrow in FIG. 12, the hinge 56 can rotate the frame body end 40c to the main body 40b in a state where the frame end 40c is allowed to rotate only upward with respect to the main body 40b. The main body 40b and the frame end 40c are usually supported so that the upper surface of the main body 40b and the frame end 40c are substantially flush with each other.

With the configuration shown in FIG. 12, if the door portion 5 is opened and the administrator or the like is performing the prize replenishment work or the like, the administrator or the like unavoidably touches the door sensor 31 and the elevating portion 41. Even when the vertical movement of the field 40 is restarted, the force acting on the body of the administrator or the like due to the vertical movement of the field 40 can be reduced by rotating the frame body end portion 40c upward. .. As a result, the administrator and the like can be further protected from the vertical movement of the field 40 by the elevating unit 41.

In particular, when the configuration shown in FIG. 12 is adopted, the administrator and the like can be further protected from the vertical movement of the field 40 even if the side cover plate 52 is omitted.

Further, the shapes of the side cover plate 52 and the notch cover plate 53 are not limited to the above-described embodiments, and various changes can be made. As an example, the notch cover plate 53 can be expanded and contracted in the vertical direction, and as an example, it can be configured in a bellows shape so that the lower end portion 53a is always in contact with the base 6. In this case, it is more preferable to attach a weight or the like to the lower end portion 53a of the notch cover plate 53 so that the expansion / contraction operation can be smoothly performed.

Further, in each of the above-described embodiments, the door sensor 31 detects the opening of the door portion 5, but the door portion 5 is provided with a lock mechanism for the housing 2, and when this lock mechanism is released, the field by the elevating portion 41 is provided. It may be controlled to stop the vertical movement of 40.

In addition, a light emitting part and a light receiving part of a photosensor are provided at both left and right ends of the opening 8 of the housing 2, and the photosensor detects intrusion into the frame 9 such as an administrator, and the elevating part 41 is used. It may be controlled to stop the vertical movement of the field 40. In particular, it is more preferable that the photo sensor detects the intrusion of the administrator or the like into the frame 9 into the gap between the field 40 and the base 6.
